To speedup the accesses to massive amount of data, heterogeneous architecture has been widely adopted in the mainstream storage system. In such systems, load imbalance and scheduler overhead are the primary factors that slow down the I/O performance. In this paper, we propose an effective file scheduling strategy HSPP that includes statistic based file classification, partition with erasure coding and adaptive dataplacement to optimize load balance and read latency on the distributed heterogeneous storage system. The experiment results show that HSPP is superior than existing strategies in terms of load balance, read latency, and scheduling overhead.
